Vermona's Fourmative Contours is a flexible envelope generator with four identical channels. Each channel of the module can be triggered independently as an attack, hold or decay phase, or linked to the next channel to create more complex voltage curves. Attack and decay are either linear or exponential and can be set on the module in a time range from 0.5 milliseconds to 37 seconds. An external control voltage can be used to significantly shorten or extend these times. In extreme cases, one phase can take up to two hours to complete!
Fourmative Contours consists of four identical envelopes with positive and negative outputs. Each unit has a trigger input for firing the envelope. This is visualized by a green LED. The second and third unit can also be launched manually with the help of the trigger button.
The envelopes can work independently as attack, hold or decay curves, depending on the mode switch position. A second switch allows the envelope to be switched between linear and exponential.
The Time knob, paired with the Slow button controls the speed of the envelope in a range from 0.5 ms to 37 seconds. This can be further shortened or extended to up to 2 hours using a control voltage at the CV input. The audio range can be reached effortlessly, allowing the module to work as an oscillator.
As soon as the envelope completed one phase, a trigger is emitted at the End Of Phase output (EOP). This makes it possible to transform the envelope into an LFO or to combine several units for a more complex envelope.
Thanks to the Sum button, subsequent envelopes can be summed, which saves a mixer. The Sum input is used to include other CV signals.
